Init absent action configs for CppCompile actions

So far only link actions were initialized in CppLinkActionConfigs. This cl
changes this class to also initialize CppCompile actions. This is needed for
our ongoing work removing hard-coded flags from Bazel and moving them into
Crosstool.

RELNOTES: None.
